Y201D Oxygen Permeation Tester

Function and usage
Y201D carries the standard of GB/T 19789-2005. It adopts Coulometry theory, High-precision sensors with over-range protection, continuous data collection, accurate and reliable data.

Standard
GB/T 19789-2005, ASTM D 3985, ASTM F2622, ASTM F 1927, ASTM F 1307, ISO 15105-2, YBB00082003, DIN 53380-3, JIS K-7126-B.

Principle
The testing chambers including upper and nether parts, the sample film is fixed between the two chambers, the high pure oxygen (O2) circulate in the upper chamber of the film, and the high pure nitrogen (N2) circulate in the nether chamber of film, the oxygen molecules get through the film and spray to nitrogen in the nether chamber, and brought by the flowing nitrogen to the sensor, and the tester then analyze the oxygen concentration as what the sensor tested and calculate the oxygen permeation quantity. But for the packing containers, the nitrogen circulates in the bottle and the air or oxygen circulates outside the container.

Features
1. It adopts international advanced electromagnetic temperature control technology and program step way can control temperature rising and lowering without any external accessory. Temperature control accuracy reach 0.01 º C
2. The humidity control adopt double air humidity control method, humidity control area is large and with high accuracy, humidity flowing stable, it avoid faults such as the big volume and more faults of pl ing humidity generator;
3. It has two calibration methods which are standard gas calibration and standard film calibration. The testing accuracy reach international advanced level and it ensure the exact testing result.
4. It has the functions of double cavity pressure control and automatic pressure balance.
5. It can judge and stop automatically.
6. It has leakage auto protection function;
7. The software operation is easy, all testing program is automatic. It records the curves automatically of the permeation rate, oxygen concentration, humidity and temperature and so on. And continuous display. It can monitor the mutual influence between the parameters, and it can monitor the testing process.
8. The functions are independent modules. The functions of testing, baselines and calibration and so on are independent. It has good ability of data analysis, and its operation is very easy;
